Why is my grid calling create for every row of data?

[Marc]

Why is my grid calling "CreateFooBar" for every row of data when delete and update are submitted? It's probably something stupid but I can't see it.

 

   @(Html.Kendo()
          .Grid<FooBarViewModel>()
          .Name("FooBarGrid")
          .Sortable()
          .Scrollable()
          .Filterable()
          .Resizable(g => g.Columns(true))
          .Columns(columns =>
          {
              columns.Command(command =>
              {
                  command.Edit();
                  command.Destroy();
              }).Width(150);
              columns.Bound(g => g.Id).Hidden();
              columns.Bound(g => g.Name).Title("Name").Width(200);
              columns.Bound(g => g.FooBarNumber).Title("FooBar<br />Number").Width(200);
              columns.Bound(g => g.CreatedBy).Width(100).Title("Created By");
              columns.Bound(g => g.CreatedDate).Width(100).Title("Created Dt");
              columns.Bound(g => g.ModifiedBy).Title("Modified By").Width(100);
              columns.Bound(g => g.ModifiedDate).Width(100).Title("Modified Dt");
          })
          .DataSource(dataSource => dataSource.Ajax()
              .Model(model =>
              {
                  model.Id(m => m.Id);
                  model.Field(p => p.CreatedBy).Editable(false);
                  model.Field(p => p.CreatedDate).Editable(false);
                  model.Field(p => p.ModifiedDate).Editable(false);
                  model.Field(p => p.ModifiedBy).Editable(false);
              })
              .Batch(false)
              .PageSize(25)
              .ServerOperation(false)
              .Read(read => read.Action("GetFooBars", "FooBar"))
              .Create(update => update.Action("CreateFooBar", "FooBar"))
              .Update(update => update.Action("UpdateFooBar", "FooBar"))
              .Destroy(update => update.Action("DeleteFooBar", "FooBar"))
              .Events(ev => ev.RequestEnd("onSave"))
              .Events(events => { events.Error("onError"); })
          )
          .ClientDetailTemplateId("collectionTemplate")
          .Events(ev => ev.Edit("onEdit"))
          .ToolBar(toolbar =>
          {
                  toolbar.Create().Text("Add FooBar");   
          })
          
          .Editable(editable => editable.Mode(GridEditMode.InLine))
                  .Pageable(pager => pager
                        .Input(true)
                        .Numeric(true)
                        .Info(true)
                        .PreviousNext(true)
                        .Refresh(true)
                        .PageSizes(new int[5] { 25, 50, 100, 200, 500 })
                    )
                    .ColumnMenu()
    )

For posterity is was because the Model Id was not getting set, so I guess the grid sees every line as new. Did this used to throw a javascript error?

Hi Marc,

Your observation is correct, the issue will occur when the ID is not assigned because in this case the error is considered as new. A missing ID never resulted in JavaScript errors, there is no reason to obligate the developer to assign IDs, in some cases, for example when the Grid is not editable, the ID is not mandatory.
